Pаrаllel_Systems_2d M.E.Lоck The cоntext fоr this question is the sаme as the previous question. 2. You are implementing a linked-list based lock algorithm on your multiprocessor (based on MCS lock) that provides fairness for threads competing for the same lock. (The below code may not be syntactically correct which should be ignored). The basic data structure is as shown below: q_node{ boolean gotit; // initialized to FALSE next; // points to the next lock requestor } Every new lock one wishes to declare in the program will do the following: L = new(q_node); // allocate a q_node L->next = nil; // nobody is using the lock A lock requestor for Lock L would do the following to execute a critical section: My_lock = new(q_node); My_lock->next = nil; My_lock->gotit = FALSE; LOCK(L, my_lock); // get lock // execute critical section UNLOCK(L, my_lock); // release lock You have implemented the lock/unlock algorithm as follows: LOCK(L, new_request) { if (L->next == nil) { L->next = new_request; // points to the last requestor new_request->gotit = TRUE; } else { L->next->next = new_request; // add new requestor to the queue L->next = new_request; // new requestor is the last requestor While (new_request->gotit == FALSE); // spin waiting for lock } } UNLOCK(L, current_request) { if (current_request->next == nil) { L->next = nil; // no one is waiting } else { current_request->next->gotit = TRUE; // signal the next requestor } } (d) (2 points) Write the code snippet to fix the UNLOCK algorithm.
